STOP-MOTION FOR DOU BLl'N-G-FRAMES.

SPECIFICATION forming part of Letters Patent No. 522,495, dated July 3,1894.

' Application filed November 7.13%. Serial No. 490. l- (No model To allwhom it may concern:

Be it known that we, ELIAs RICHARDS and ROBERT LUCAS, both of NewOrleans, in the parish of Orleans and State of Louisiana, have inventeda new and Improved Stop-Motion ple and durable in construction, veryeffective and automatic in operation, and arranged for preventing singlestrands from passing through the drawing rollers in case one of thestrands breaks.

The invention consists of two rollers be- .tween which pass strands,slivers or sheets, and locking devices provided with movable andstationary or fixed portions for holding the rollers immovable, the saidmovable portions normally tending to lock with the said fixed portionsand held in disconnected posi tion by the strands, slivers or sheets,whereby on the breaking of one of the strands, slivers or sheets therollers will be held immovable;

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a sectionalside elevation of thesame as applied; and Fig. 3 is a side elevation ofthe improvement. 7

As illustrated in Fig. 2, the stop motion is arranged between thedrawing rollers A, and the bobbins B and B, and the said stop motion isprovided with a'suitably constructed frame 0, having slotted standards0, in which are journaled the shafts D and E of rollers D and E, locatedone above the other and fluted longitudinally to form toothed or gearwheels, as will be readily understood by reference to Fig. 2. Thestrands F and F, unwinding from the bobbins B and B respectively, passbetweenthe rollers D and E near the sides thereof, as is plainly shownin Fig.

1, so that the two rollers are held out of peripheral contact. 1

The strands F and F, are held in proper position between the rollers Dand E, by the guide G, through slots in which pass the said strands, thestrands after leaving the rollers passing through the drawing rolls A,as will be readily understood by reference to Fig.2. The guide G isfitted to slide loosely in suitable guideways formed in the rear part ofthe standards 0' as plainly shown in Figs. 2 and 3. On theends of theshaft E of the uppermost roller E, are secured the pins H, H extendingradially and in opposite directions, the said pins passing normally, thefixed stop pins I and 1 respectively projecting from the sides of thestandards 0, C.

Now, in case one of .the strands F or F breaks or runs thinner betweenthe rollers D, E, then that side of the uppermost roller E, will movecorrespondingly downward,whereby the corresponding pin H or H will movein contact with the corresponding stop pin I or I, thus forming aninterlocking device and thereby preventing further rotation of the saidroller, and consequent breaking of the strands between the rollers andthe drawing rollers A, so that no single strand whatever, can passbetween the drawing rollers.

It is understood that the drawing rollers A in pulling on the strands,cause the rollers D and E to revolve, and when the uppermost roller Emoves downward as above described, its teeth engage the teeth of theother roller D so that both are locked in position and consequently abreaking of the other remaining strand will take place between thelocked rollers and the drawing rollers A.

Having thus fully described our invention, we claim as new and desiretosecure by Letters Patent- 1. A stop motion comprising two rollersbetween which pass the strands or slivers, and locking devices providedwith movable. and stationary or fixed portions for holding the rollersimmovable, the said movable portions normally tending to lock with thesaid fixed portions and held in a disconnected position by the strandsor slivers, whereby, by the breaking of one of the strands or sliversthe rollers will be held immovable, substantially as shown anddescribed.

2. A stop motion comprising two rollers arranged one above the other andbetween which pass the strands or slivers, the upper roller resting byits weight on the material, a pin on the shaft of the said upper roller,and a stop pin adapted to be engaged by the roller pin whenever one ofthe strands breaks or decreases in thickness, substantially as shown anddescribed.

3. Astop motion comprising two fluted rollers arranged one above theother and mounted to turn loosely, the upper roller resting by itsweight on the strands passing between the rollers, pins secured on theshaft of the uppermost roller, and fixed stop pins projecting from theframe and adapted to be normally passed by the said roller pins, butengaged by the same when one of the strands breaks or decreases inthickness, substantially as shown and described.

4. A stop motion interposed between the drawing rollers and the bobbins,and comprising a frame having slotted standards, fluted rollersjournaled loosely in the said slotted standards and arranged one abovethe other, pins held on the shaft of the'nppermost roller, stop pinsprojecting from the standards of the said frame and normally passed bythe said roller pins but engaged by the same on the breaking of one ofthe strands or a decrease of thickness, and a guide held loosely on theframe for guiding the strands between the rollers near the ends thereof,substantially as shown and described.
